It makes perfect sense to me. We know that the Glovis Cosmos is going to Southhampton UK. The first expected delivery dates in Europe are scheduled from around the 13th of Oktober. (mine is) And I know from this Forum that there is one scheduled in Denmark and Norway from around the 13th of Oktober as well. We know for a fact that the Crystal Ray is filled with New Model 3 and Model Y.
The Crystal Ray is expected to dock in Zeebrugge around the 7th of Oktober. There is no other ship that could make the expected delivery date, so it makes sense doesn't it?
